Description

The apparatus for controlling connection of automatic bobbin winder

The present invention relates to the apparatus for controlling connection of the automatic bobbin winder that the joint number of times can change arbitrarily.

In the automatic bobbin winder that is provided with a plurality of spoolers side by side, known type has each spooler to have piecing devices separately, and the operation chassis that piecing devices perhaps are housed can move along a plurality of spoolers, or the like.

This automatic bobbin winder is in operation when detecting the defective that tufted yarn and so on is arranged in the yarn, and just force disconnect yarn again the top yarn of yarn tube one side with connect for the bottom yarn of yarn tube one side, thereby is removed the defective on the yarn.In addition, except tufted yarn, breaking and giving under the situation that does not have yarn and so on the yarn tube, do not moving, also can finish above-mentioned same joint action owing to detect yarn.

If joint has successfully been finished in the action of above-mentioned joint, just begin to batch normally once more, if in the joint action of stipulated number, do not connect head, then machine demonstrate can not joint signal, stop to batch, wait for that the operator handles.

In above-mentioned conventional device, the memory of the joint frequency of failure is finished with the mechanical type cam mechanism, the every crank motion of relay pipe once, Lian Dong memory cam just rotates a pitch with it, when the joint failure reaches predetermined times, the memory cam just turns to certain angle, makes expression can not connect the parts action of head.

Therefore, the setting of joint action multiplicity will change the number of times of setting by the decision of memory cam, just must change memory components such as memory cam, and this is pretty troublesome work.Particularly, along with the appearance of the production system of multi-varieties and small-batch, because the kind of yarn changes continually, the joint of yarn has very difficult, also has easily, so the device of wishing to have the joint number of times of setting also can change along with the kind of yarn at an easy rate.The applicant's first to file once a kind of number of times with electrical metering joint failure, (spy opens clear 64-28179 can to make the apparatus for controlling connection that spooler stops on the number of times of setting arbitrarily,, but this device exists the problem that will reequip significantly when using on existing installation.

Therefore, the purpose of this invention is to provide a kind of apparatus for controlling connection of automatic bobbin winder, it can be applied on the existing installation easily, and the mode of the joint number of times of change setting is very simple.

For achieving the above object, the invention is characterized in to comprise following parts: with the number of times of mechanical system gage nipple failure, the memory cam that when the number of times of regulation, spooler is stopped; Remove the work of above-mentioned memory cam or make it proceed the magnet coil of work according to the success or not of joint; And, till the number of times of setting, just remove controller to the control of above-mentioned magnet coil with the electric means gage nipple frequency of failure.

When the spooler joint was failed, controller measured its number of times with electric means, just removed the control to magnet coil till the number of times of setting.Therefore, in the phase at this moment, the memory cam no longer moves, and the joint frequency of failure is since then measured by the memory cam again, on the number of times of regulation spooler is quit work.

Not only adorn magnet coil but also the memory cam is arranged because in existing spooler, also have, in this spooler, as long as additional controller is just enough,, can change the number of times of the joint failure of setting simply so the present invention can be conveniently used in existing equipment.

Describe one embodiment of the present of invention with reference to the accompanying drawings in detail.

The simple declaration of accompanying drawing:

Nomenclature:

The 1-spooler; 16-remembers cam; The 17-magnet coil; The 24-controller.

Among Fig. 1, the 1st, a plurality of being arranged side by side on the direction perpendicular to paper formed the spooler of automatic bobbin winder.In this spooler 1, supply eased off yarns Y on the yarn bobbin 2 from the below, through air ring energy disperser 3, apron pin 4, scrubber (being also referred to as yarn defect grabber) 5 by means of reciprocating traverse cylinder 6, is wound onto batching on the yarn tube 7 of placement.

At this moment, if scrubber 5 detects the fault in the yarn, then be contained in scrubber 5 in-to-in cutters and just move, the moving yarn of force disconnect, one side stops to batch, suction inlet 8 work on the other hand, the top yarn that batches yarn tube 7 one sides is imported in the piecing devices 9, and 10 of relay pipe will import for the bottom yarn of yarn bobbin 2 one sides in the above-mentioned piecing devices 9, with these piecing devices 9 upper and lower yarn be connected, if the joint success just restarts to batch.

In above-mentioned spooler 1, be provided with the cam mechanism that is used for the joint action, in Fig. 2, if disk cam 11 begins from the solid line position turning clockwise simultaneously with above-mentioned joint action, when forwarding 346 ° to, the driven voller 13a that is bestowed by spring 12 on the 1st lever 13 of pulling force embeds in the recessed race 11a, making the 1st lever 13 is that fulcrum is swung to the right with axle 14, pin 15a on the 2nd lever one end is embedded among the elongated slot 13b of first lever, 13 ends, so the 2nd lever 15 is that fulcrum turns left with the axle of not representing in scheming, make the ratchet 15b that sends to of its other end move, thereby make memory cam 16 turning clockwises shown in Fig. 3, the pitch of advancing.Then,, the 1st lever 13 is swung left, resetted so send ratchet 15b to because the driven roller 13a on the 1st lever 13 contacts with protruding 11b on the cam.

At this moment, if the joint success, reciprocating traverse yarn tube 6 has rotated, because magnet coil 17 remains on " disconnection " position, block 18 just turns left, and memory cam 16 is not caught by ratchet, just be returned to original position by means of the spring of not representing among the figure.If the joint failure is then opposite, by means of the detection signal of 5 pairs of yarns of scrubber, magnet coil 17 is connected, because block 18 is to right-hand rotation, just memory cam 16 is caught by ratchet under the state of a pitch that advances.

Fail as joint, just carry out joint again, when the joint frequency of failure reaches when resembling among the embodiment predetermined 3 times, memory cam 16 is contacting with an end 19a of the 3rd lever 19 shown in imaginary line among Fig. 3 like that just, making this root the 3rd lever 19 is that fulcrum turns left with axle 20, makes the button (also claiming yellow button) 21 that expression can't joint show the front at spooler 1 especially by means of the other end 19b of the 3rd lever 19.Owing to the 3rd lever 19 is provided with the spring 22 that surpasses fulcrum because of the rotation of lever,, and remain under this state so the yellow button 21 that protrudes can not be pulled.In addition, by means of the other end 19b of the 3rd lever 19, make switch 23 disconnect, so, owing to when stopping spooler 1, also cut off the electric current of magnet coil 17, so block 18 rotates to left, ratchet is grabbed and is incessantly remembered cam 16, and the memory cam resets.

Be provided with controller 24 in the spooler of this structure, controller up to the number of times of setting, is just removed the control (outage) to above-mentioned magnet coil with the number of times of electric means gage nipple failure.The control circuit of this controller 24 has repeating coil 25 as shown in Figure 5 in the circuit, when joint action finishes and scrubber 5 when not detected yarn, it is just by excitatory, links to each other with magnet coil 17 by a sequencer 26 in the adjacent side of this relay tip 25a.Sequencer 26 adopts semiconductor memory, as has set the joint number of times, just it can measure.When the contact 25a of memory device connection, it is counting just, till the number of times of setting, wherein can make magnet coil 17 outages each time.

Fig. 6 represents the work-hours curve of above-mentioned magnet coil 17.The magnet coil that in the past was used to remember cam has rotated that time of 312 ° at garden dish cam, just outage immediately of coil in the time of the cylinder starting, if joint success, it is constant promptly to keep outage, if joint failure, then forward to and that time of 332 ° coil is connected, memory cam be booked after the pitch (holder resets) of advancing by the detection signal of scrubber 5 at cam.In contrast, magnet coil 17 among the application has rotated that time of 312 ° at disk cam 11, though Duan Dian action immediately is with above-mentioned identical, if but from 312 ° of cylinder starting (journey of traversing cylinder begins to rotate) this be carved in 332 ° the interval, do not failed owing to there being yarn to judge joint in the scrubber 5, so from 332 ° at the moment approximately in 360 ° of this section period t, just make coil blackout forcibly.Controlled by the timer of 26 li of sequencers the opening time of this magnet coil 17.Therefore, changeed that time of 346 ° at disk cam 11, even will push memory cam 16, because magnet coil 17 outages, it is not caught by ratchet yet, can not advance.

Work below with reference to the explanation of the workflow among Fig. 4 the foregoing description.When owing to yarn detects (S1) when not having yarn in the scrubber in reasons such as coiling process break, just carry out the action (S2) of joint, the cylinder starting.Then, judge (S3) to whether yarn is arranged in the scrubber 5, in some cases, the electron storage device of memory cam 16 and sequencer 26 resets (S4), begins to continue to batch yarn (S5).

In scrubber 5, do not have under the situation of yarn, then whether the setting joint number of times of being remembered in the electron storage device is equated to judge (S6) with the gage nipple number of times, as measure number of times and be less than set point number, then force magnet coils 17 in time gap t, cut off the power supply (S7) by controller 24, meanwhile, the electron storage device is write down number of times (S8).Surpassing under the situation of set point number, judging with mechanical system whether the gage nipple number of times of being remembered in the memory cam 16 equates (S9) with set point number (3 times) earlier.If less than set point number, then be originally the same of connection with magnet coil 17, memory cam 16 is write down number of times (S10).If the memory cam is during to set point number,, this spooler 1 prominent electron storage device, remember cam 16 reset together (S12) just remember that with memory cam 16 the yellow button 21 of the action interlock of set point number protrudes (S11).

Like this, when the joint failure takes place in spooler 1, the number of times that controller is promptly failed with the electric means metering, before set point number, remove the work of magnet coil 17, during this period, memory cam 16 is not worked, its only metering reach the joint frequency of failure after the set point number of controller, arrived predetermined times after, spooler 1 is stopped.Therefore,, just can set the joint number of times arbitrarily, simultaneously,, just can change the set point number of joint at an easy rate by means of the setting number of the electron storage device that changes controller 24 by means of controller 24 and memory cam 16 are combined.

In addition,, also have existing magnet coil 17 that memory cam 16 is arranged again because in existing spooler, thus for such spooler as long as additional controller 24 is just much of that, make the present invention can be advantageously used in existing installation.

Moreover in an embodiment, yellow button occurs when supposing continuous No. 5 joints failure, so both can make magnet coil 17 double disconnections at the beginning, also can write down double joint failure by memory cam 16 at the beginning after, make magnet coil 17 outages again.

In sum, owing to also there is existing magnet coil that the memory cam is arranged again in the existing spooler,, make the present invention can be advantageously used in existing installation, change the joint number of times of setting easily so get in the mechanism as long as additional controller is just much of that this.
